How Search Engines Works Liebman

As i read this article I had a better understanding of how search engines work. When your just a regular search engine user you really do not know how your searches end up that way. As i saw in the article i was not aware of the ranking system that search engines like google and bing had. Now looking deeper into the matter as it says in the article most ranking is taken by the amount of traffic that those pages have. Seeing it this way I am not sure that popularity is always a good thing. What if there is a page where information much more informative then those pages ranking on the top?Although this is a question that could raise awareness to such issues the ranking system seems to work but it does have its flaws.
